因此一些UPS電源維護(hù)小常識(shí)就顯得特別的重要，如：防止機(jī)箱里面灰塵堆積，定期保養(yǎng)電源里面的蓄電池等等，這些維護(hù)小常識(shí)往往能極大地延長(zhǎng)UPS電源的使用壽命，減少維修麻煩。（2）保持適宜的環(huán)境溫度：影響蓄電池壽命的重要因素是環(huán)境溫度，一般電池生產(chǎn)廠家要求的比較好環(huán)境溫度是在20－25℃之間。雖然溫度的升高對(duì)電池放電能力有所提高，但付出的代價(jià)卻是電池的壽命**縮短。據(jù)試驗(yàn)測(cè)定，環(huán)境溫度一旦超過25℃，每升高10℃，電池的壽命就要縮短一半。達(dá)不到規(guī)定的環(huán)境要求，其壽命的長(zhǎng)短就有很大的差異。另外，環(huán)境溫度的提高，會(huì)導(dǎo)致電池內(nèi)部化學(xué)活性增強(qiáng)，從而產(chǎn)生大量的熱能，又會(huì)反過來促使周圍環(huán)境溫度升高，這種惡性循環(huán)，會(huì)加速縮短電池的壽命。（3）定期充電放電：UPS電源中的浮充電壓和放電電壓，在出廠時(shí)均已調(diào)試到額定值，而放電電流的大小是隨著負(fù)載的增大而增加的，使用中應(yīng)合理調(diào)節(jié)負(fù)載，比如控制微機(jī)等電子設(shè)備的使用臺(tái)數(shù)。一般情況下，負(fù)載不宜超過UPS額定負(fù)載的60%。在這個(gè)范圍內(nèi)，電池的放電電流就不會(huì)出現(xiàn)過度放電。UPS因長(zhǎng)期與市電相連，在供電質(zhì)量高、很少發(fā)生市電停電的使用環(huán)境中，蓄電池會(huì)長(zhǎng)期處于浮充電狀態(tài)。UL33-0800L不間斷電源ups維修哪家服務(wù)好南昌穎頓科技有限公司率先垂范，廉潔奉公。</p><div
